reservoirs

New Delhi: The water storage available in 91 major reservoirs of the country for the week ending 11 May was 37.718 billion cubic metres (bcm), which is 24% of their total storage capacity. This percentage was at 26 for the week ending 4 May. The level of 11 May was 125% of the storage of the corresponding period of last year and 103% of storage of average of the last 10 years.

The total storage capacity of these 91 reservoirs is 157.799 bcm, about 62% of the total storage capacity of 253.388 bcm which is estimated to have been created in the country. Thirty-seven out of these have hydropower benefit with an installed capacity of more than 60 MW.

Reservoirs in northern areas

The northern region includes the States of Himachal Pradesh, Punjab and Rajasthan. There are 6 reservoirs under the Central Water Commission (CWC) monitoring with a total live storage capacity of 18.01 bcm. The total live storage available in these storages is 4.34 bcm, which is 24% of their total live storage capacity. The storage during the corresponding period of last year was 20% and average storage of last 10 years during the corresponding period was 29% of the live storage capacity of these reservoirs. Thus, storage during the current year is better than the corresponding period of last year but is less than the average storage of the last 10 years during the corresponding period.

East

In Jharkhand, Odisha, West Bengal and Tripura, there are 15 reservoirs under CWC monitoring, having a total live storage capacity of 18.83 bcm. The total live storage available in these reserves is 6.92 bcm, which is 37% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 27% and average storage of the last 10 years during the corresponding period was 23% of the live storage capacity. Thus, storage during the current year is better than the corresponding period of last year and is also better than the average storage of the last 10 years during the corresponding period.

West

The States of Gujarat and Maharashtra have 27 reservoirs under CWC monitoring, with a total live storage capacity of 27.07 bcm. The total live storage available here is 7.78 bcm, 29% of the total live storage capacity. The storage during the corresponding period of last year was 16% and average storage of the last 10 years during the corresponding period was 29% of the live storage capacity of these reservoirs. Thus, storage during the current year is better than the storage of last year and is equal to the average storage of the last 10 years during the corresponding period.

Central region

The States of Uttar Pradesh, Uttarakhand, Madhya Pradesh and Chhattisgarh have 12 reservoirs under CWC monitoring, having a total live storage capacity of 42.30 bcm. The total live storage available is 14.36 bcm, which is 34% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 25% and average storage of the last 10 years during the corresponding period was 22% of their live storage capacity. Thus, storage during the current year is better than the storage of last year and is also better than the average storage of the last 10 years during the corresponding period.

South

The southern region includes the States of Andhra Pradesh, Telangana, AP&TG (2 combined projects in both the States) Karnataka, Kerala and Tamil Nadu. There are 31 reservoirs under CWC monitoring, with a total live storage capacity of 51.59 bcm. The total live storage available is 4.32 bcm, 8% of the total live storage capacity of these reservoirs. The storage during the corresponding period of last year was 12% and average storage of the last 10 years during the corresponding period was 19% of their live storage capacity. Thus, storage during the current year is less than the corresponding period of last year and is also less than the average storage of the last 10 years during the corresponding period.

Government action last year

States with better storage than what they had last year for the corresponding period are Punjab, Rajasthan, Jharkhand, Odisha, West Bengal, Gujarat, Maharashtra, Uttar Pradesh, Madhya Pradesh, Chhattisgarh, and Telangana. States having as much storage as they had last year for the corresponding period are AP&TG. States having lesser storage than last year for the corresponding period are Himachal Pradesh, Tripura, Uttarakhand, Andhra Pradesh, Karnataka, Kerala, and Tamil Nadu.
